Subject J2SE 5 features
Date Tue, 12 Jul 2005 00:35:47 GMT
Hi, all.  After attending a few JavaOne sessions I saw there were a lot 
of things we could do with J2SE 5.  I tried, unsucessfully, to search 
the archives for a discussion about how we can start taking advantage of 
J2SE 5 features.  Can we use J2SE 5 features?  What processes/mechanisms 
do we have to follow to do this.  Do we need to implement new pluggable 
modules/services that are specific to J2SE 5 so that versions of Derby 
can be backward compatible with JDK 1.4?

Here's a short list of possible uses of features currently not in use. 
Note that some of these are available even in JDK 1.4...

- Using NIO for network I/O
- JMX for configuration and administration (yes, I know, big task)
- Use concurrent collections for better concurrency
- Use the ExecutorService for network server threads
- Use the ScheduledExecutorService from the new concurrency utilities 
for TimerTasks
- Log trace messages using message queues for better performance during 
- Asserts
- Generics
- Chained exceptions
